The Brandt Europe company, a subsidiary of the American company that is an agricultural leader for Europe, the Middle East, and Africa, has managed to increase the production yield of zucchini by one to two kilos per square meter using two biostimulant solutions.
The trial, which was carried out on a 10,000-square-meter greenhouse farm planted with 5,000 plants of zucchini of the Victoria variety in Ruescas (Almeria), had three objectives: significantly increasing production, increasing the number of fruit curdles, and comparing the plants' growth regarding the control group to analyze the separation of internodes.
After applying four treatment passes, once a week, with a combination of two biostimulants – Brandt In-Vigo and Brandt Plant Start– which were developed in the laboratory that the company has in Carmona (Seville), the zucchini had an average increase in the number of pieces per cut of about six kilograms per line when compared to the control group. This means that, on average, the total production increased by one to two kilos per square meter.
In addition, the treated line yielded a greater number of female flowers with more force, greater vigor, and more length. However, the distance between the internodes did not increase, which leads to more zucchini pieces collected per plant. Another interesting conclusion of this trial is that the levels of fungal diseases or pests after the treatments didn't increase when compared to the control group.
This increase in production is especially significant for the Spanish zucchini sector, which in 2018 exported 361,000 tons of zucchini worth 311 million euro, mainly to France (116,000 tons), Germany (82,000 tons), the United Kingdom (40,000 tons), and the Netherlands (more than 39,000 tons). Almeria is Spain's main producer of zucchini. In fact, more than eight out of ten zucchini that Spain sold abroad were exported by companies from the province of Almeria.
